Research that brings together electronic health record (EHR) data across multiple health systems can be greatly facilitated by the HCSRN’s Virtual Data Warehouse (VDW). Information and tools to help investigators discover the potential of the VDW and navigate obstacles to using it for health system-based research are offered below.
The VDW and How to Use It - A 6-page introduction to the HCSRN Virtual Data Warehouse (VDW) for Investigators. This includes an overview of the distributed data model, its data areas and structure, and steps for using it.
Examples of VDW Projects - A great deal of research can be conducted using only VDW data. More commonly VDW data supplements other data gathered from subjects (e.g., surveys, research specimens). A list of example projects is provided
